The Lens Cap "Super-Snap" from Hama are the best alternative / replacement for the original cover. Special feature of the Super-Snap are the "internal" key for unlocking the lid. While this is a bit strange in the beginning, because you have to rely on the frontal Obejektiv to uncover, but has the advantage that the lid can be unlocked in the camera bag not accidental. What helps me the beautiful cover with the brand logo, when this is all over the camera bag on the road, but not on the front lens, where it should be! Quality: I have some of these cover for years in use - none went so far defective - When the original cover my Sony after six months, the suspension was broken. I will in the future to a new lens to order like the "Super-Snap" and to not tease me with the original lids or lids with "external buttons".
